STEAM FITTING Filed April 13, 1923 2 Sheets-Sheet 2 l the steam, fittin Patented Oct. 28, 1 930 ALONZO Amman, oFIBELoI'T, ,WISGONSIN s'rEA rimming My invention relates to steam fittings, .par-

' ticularly steamIfittings for usetin connection with dryingcylinders; of paper making machines. Y

6 a One of the objects of invention is to provide a simple, practical and effective,

steam fitting, particularly of the class mentioned.

v Another object oi the invention is to pera V 10 mit the adjustment of the fitting so as to secure efi'ective drainage of thedrying cylinder. V v

Referring to the drawings, Fig. 1 is a side elevation of a drying cylinder equipped with g embodying my present invention; Fig. 2 is an end elevation of the same;

Fig. 3 is a side elevation partly in section v of a portion of the device; and

Fig. 4 is an end elevation of the same. Referring to the drawings I show a drying cylinder 1 which is for use in a paper making machine and is .shownmounted in frame pieces 2 and 3, the cylinder ends having hub portions 3*, 3 A steam inlet 4 is provided at one end 011 a head 1 to let steam into the interior 5 of the drying cylinder. A drain pipe 6 is also shown extending intothe same end of the cylinder and extended down in the interior to the bottom of the same in order to act as a siphon or suction tube to remove moisture from the interior of the cylinder. I I

The steam inlet 4 connects with a downwardly extending steam supply pipe 8 which is understood to be suitably connected for supplying steam to the interior of the'cylinder 1 to heat the same; .To permit adjust ment of the cylinder 1 relatively to pipe 8 an inlet pipe connection 9 is provided and pipes 8 and 9 are provided with'cooperating joint v pipe forming members 10 and 11, whereof the member 10 hasa conical face 12 and the mem- 4 ber 11 a cup face 13, in which the face 12 may fit with a suitable layer of packing or other material 14 in between, bolt 15 and spring 15 holding these parts together to make a tight joint. The pipe connection 9 is preferably formed as a part of a connecting member 23 which is held tight to head 1 of 1923. Serial 110,631,858.

cylinder 1 by bolts 15 controlled by springs 16, and passing through two arms 17, 17-011 said member 23. Pipe 6 extends through member 23 and into head 18 to which it is secured by'bolt 19. Head l8is stationary but.

vrotatablyadjustable'and has a disk member 21; which cooperates with-a disk 22 on member 23,-disk 21 having a pointer or arrow 24 and. member T22 having graduations 25 so that the relative position of said membersQl and'22 may be shown. Thus by turning the member-18 the position .ofthe'drain plpet'i in cylinder lrmay be changed, and also the position of said pipe may be indicated. Thus ifa change is madein the connection to the drain pipe or if adjustments aremade in the drying cylinder or in the pipe connections, a workman may put the cl-rain"v pipe 6 :back. in-just; the position itwas previously,

: by adjusting member 21' so thatf arrow 24;

comes into registerwith the same graduation=25. ,j Hence the placing of the drain pipe 6 in a'wrong position, thatis in some posi: Ttion other than a. position at the bottom of cylinder 1, l is avoided, and the adj ustment, -of said pipe to the right place is always se- ;cured-,, thereby alwaysassuringthe Withdrawal of moisture' from the cylinder 1 V in the most efficient manner, The A adjustment of member 2.1 is permitted, by means of circu- '1a'r;slot s 29 and: boltsqigOadapted to pass through said slots. v V v l j jInorderto permit adjustment of the dry- ]ing cylinder 1 and other parts an adjustable joint is made between drain outlet or. dis, charge pipe-31 andmember 23. This consists of a cone shaped memberl32 and a cup shaped member 33, into which member 32' may fit with intervening packing 34. This joint is held tightjjby bolt35and spring 36 n1en1ber23 is held against sidewise motion by fingers17",on arms 17 and 17 on'member23 engaging annular surface 1 3.011 ring, 1? on head I a imodifications may be made without depart- .ing ififomjthe spirit of the invention.
